What is your explanation?
I understand your point. You're saying that if complexity implies a designer, why doesn't the designer of the complexity have a designer?
And I'm saying, maybe he does, if as you say he's necessarily "complex" (although I'd like to know how you know).
But the real issue is the link between complexity and design. Is the kind of complexity we find in life evidence (not necessarily proof) of design or not? And you're the guy who's dodging that issue, buddy. Capisci?
And in saying "maybe he does", you create a cosmic hall of mirrors of infinite scope and proportion.
An endless string of continuously designing designers, each with a great complexity than his creation.
